A nitride film is deposited and a first oxide film is deposited that contains an impurity having a second conductivity type that differs from the first conductivity type. The first oxide film, the nitride film, and the second oxide film are etched to form a contact hole. An epitaxial growth process is carried out form a first pillar-shaped silicon layer in the contact hole. The nitride film is removed and epitaxial growth process is performed to form an output terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for producing a semiconductor device","description":"A method for producing a semiconductor device includes depositing an oxide film containing an impurity having a first conductivity type on a substrate.
